Querying Ozone

Reference guide for the 10 Ozone MCP tools available through the skywatch-mcp server. Covers parameter patterns, filter combinations, pagination, and common recipes. Load this skill when you need to interact with the Ozone moderation API.

Delegation Pattern

Ozone read queries (queue pulls, event history) and write actions (labelling, acknowledging, escalating) should be dispatched to subagents rather than executed inline by the supervisory agent. Pass the subagent the parameters it needs — subject, label, comment, batchId — and let it execute. This preserves the supervisory agent's context window for decision-making.

• Read queries: Dispatch to the data-analyst subagent with the research question. Receive a structured summary.
• Write actions: Dispatch to the general-purpose-mini subagent with a pre-built action manifest. Mechanical execution, no judgment required.

Credentials

Ozone tools require five environment variables: OZONE_HANDLE, OZONE_ADMIN_PASSWORD, OZONE_DID, OZONE_PDS, OZONE_SERVICE_URL. All are set in .envrc in the project root. All tools fail gracefully with a clear error if credentials are missing.

Auth goes through the PDS (via atproto-proxy header), not directly to the Ozone service. The ozoneRequest helper automatically retries on ExpiredToken with a session refresh — no manual retry logic needed.

Subject Format

All tools accept a subject parameter. Two formats:

• Account-level: Pass a DID (did:plc:...). Actions apply to the account.
• Post-level: Pass an AT-URI (at://did:plc:.../app.bsky.feed.post/...). Requires cid parameter — resolve it via com.atproto.repo.getRecord if not already known.

When in doubt, use account-level subjects. Post-level operations are for labelling or acting on specific content rather than the account as a whole.

mcp__skywatch-mcp__ozone_query_statuses

Query the moderation queue. Returns subjects with their current review state, tags, and metadata.

Parameters (all optional):

Parameter	Type	Description
subject	string	Filter to a specific DID or AT-URI
review_state	string	Filter by review state (e.g., open, escalated, closed)
tags	array	Filter by tags applied to subjects
takendown	bool	Filter for subjects that have been taken down
appealed	bool	Filter for subjects with active appeals
limit	number	Results per page
cursor	string	Pagination cursor from previous response
sort_field	string	Field to sort by (e.g., lastReportedAt, lastReviewedAt)
sort_direction	string	asc or desc

Common recipes:

Goal	Parameters
Recent user reports	sort_field: "lastReportedAt", sort_direction: "desc", limit: 20
Open appeals	appealed: true, sort_direction: "desc"
Unreviewed subjects	review_state: "open", sort_field: "lastReportedAt", sort_direction: "desc"
All reports for one account	subject: "did:plc:..."
Tagged for follow-up	tags: ["follow-up"], review_state: "open"
Escalated subjects	review_state: "escalated"

Pagination: When results exceed limit, the response includes a cursor. Pass it in the next call to get the next page. Continue until no cursor is returned.

mcp__skywatch-mcp__ozone_query_events

Query moderation event history. Returns a log of all moderation actions taken on subjects.

Parameters (all optional):

Parameter	Type	Description
subject	string	Filter to a specific DID or AT-URI
types	array	Filter by event type (e.g., label, acknowledge, comment, escalate, tag, mute, report)
created_by	string	Filter by moderator DID
created_after	string	ISO datetime — events after this time
created_before	string	ISO datetime — events before this time
added_labels	array	Filter for events that applied specific labels
has_comment	bool	Filter for events with comments
limit	number	Results per page
cursor	string	Pagination cursor
sort_direction	string	asc or desc

Common recipes:

Goal	Parameters
Full moderation history for an account	subject: "did:plc:...", sort_direction: "asc"
Recent label actions	types: ["label"], sort_direction: "desc", limit: 50
Events by a specific moderator	created_by: "did:plc:...", sort_direction: "desc"
All actions in a time window	created_after: "2026-04-01T00:00:00Z", created_before: "2026-04-28T00:00:00Z"
Check if a label was ever applied	subject: "did:plc:...", added_labels: ["spam"]
Events with moderator notes	has_comment: true, sort_direction: "desc"

Write Tools

Common Conventions

batchId: All write tools accept an optional batchId (UUID string). Use a single batchId to group related operations — e.g., all labels applied during one queue triage session share one batchId. Generate a new UUID for each logical batch of work. Different types of actions (labelling vs. acknowledging) within the same session may use the same batchId if they're part of the same workflow.

comment: Most write tools accept an optional comment. Use it to record reasoning for the action. Comments become part of the permanent moderation event history.

Metadata: All write tools automatically include modTool metadata (name: "skywatch-mcp") for traceability.

mcp__skywatch-mcp__ozone_label

Apply or remove a moderation label.

Parameter	Required	Description
subject	yes	DID or AT-URI
label	yes	Label string to apply or remove
action	yes	"apply" or "remove"
cid	post-level only	Content hash for AT-URI subjects
comment	no	Reasoning for the label action
batchId	no	UUID grouping related operations
duration_in_hours	no	For temporary labels — auto-expires after this duration

When to use: After reviewing evidence and determining a policy violation. Use duration_in_hours for temporary labels on borderline cases or time-limited enforcement.

mcp__skywatch-mcp__ozone_acknowledge

Move a subject from open/reported to reviewed. Closes reports.

Parameter	Required	Description
subject	yes	DID or AT-URI
acknowledgeAccountSubjects	no	true to acknowledge all reported content by this account
comment	no	Reasoning
cid	post-level only	Content hash
batchId	no	UUID

When to use: After reviewing a subject and completing all actions (labelling, no-action, etc.). Acknowledgement closes the report in the queue. Use acknowledgeAccountSubjects: true to bulk-close all reports for an account in one call.

mcp__skywatch-mcp__ozone_comment

Add a comment to a subject's moderation record.

Parameter	Required	Description
subject	yes	DID or AT-URI
comment	yes	Comment text
sticky	no	true for persistent visibility in the moderation UI
cid	post-level only	Content hash
batchId	no	UUID

When to use: To record observations, investigation notes, or context that other moderators should see. Use sticky: true for important context that should remain visible (e.g., "this account is part of a coordinated network — see investigation report YYYY-MM-DD").

mcp__skywatch-mcp__ozone_escalate

Escalate a subject for higher-level review.

Parameter	Required	Description
subject	yes	DID or AT-URI
comment	no	Reasoning for escalation
cid	post-level only	Content hash
batchId	no	UUID

When to use: When a subject requires review by someone with more authority or context — policy edge cases, high-profile accounts, potential legal issues.

mcp__skywatch-mcp__ozone_tag

Add or remove tags from a subject's moderation record.

Parameter	Required	Description
subject	yes	DID or AT-URI
add	no	Array of tag strings to add
remove	no	Array of tag strings to remove
comment	no	Reasoning
cid	post-level only	Content hash
batchId	no	UUID

At least one of add or remove is required.

When to use: For categorisation, tracking, or workflow routing. Tags are searchable via mcp__skywatch-mcp__ozone_query_statuses.

mcp__skywatch-mcp__ozone_mute

Mute a subject for a specified duration.

Parameter	Required	Description

When to use: When a user has appealed a moderation action and you've reviewed the appeal. The comment is mandatory — document why the appeal was upheld or denied.

Gotchas

• Credentials via direnv — non-secret Ozone settings live in .envrc; OZONE_ADMIN_PASSWORD lives in secrets/ozone.env, loaded by .envrc via source_env_if_exists. The skywatch-mcp Polytoken MCP server should be launched through direnv exec /path/to/project ... so Ozone tools receive OZONE_HANDLE, OZONE_ADMIN_PASSWORD, OZONE_DID, OZONE_PDS, and OZONE_SERVICE_URL at server startup.
• Auth route: PDS proxy, not direct Ozone connection
• cid required for post-level: If you have an AT-URI but no cid, resolve it first via com.atproto.repo.getRecord
• Auto-retry on token expiry: The ozoneRequest helper handles ExpiredToken automatically — don't add manual retry logic
• Acknowledge closes reports: Acknowledgement is the "done" action — use it after all other actions are complete, not before
• batchId is optional but recommended: Makes audit trails traceable — group related operations under one UUID
